Abstract: 1435813 Adjusting the moisture content of tobacco HAUNI-WERKE KORBER & CO KG 17 Aug 1973 [18 Aug 1972] 38905/73 Heading A2C  In a method for humidifying tobacco or another material of the tobacco-processing industry in which moisture is transferred to the tobacco as it is conveyed by means of heated and humidified air or other gas which is guided through a conditioning zone in concurrent flow with the tobacco, the final moisture content of the tobacco is measured and the amount of moisture contained in the heated gas is automatically controlled dependent on the measured value of the final moisture content of the tobacco for the purpose of keeping the final moisture content of the tobacco-constantly at a desired value. As shown in Fig. 1 a control arrangement 16 (not shown in detail) determines that the flow per unit time of tobacco 20 supplied by conveyor type weigher 14 is constant. A shoot 26 above a driven winnower drum 33 serves for supplying tobacco, to the inlet side A of a moisture drum 21. Another shoot 27 discharges the tobacco at the outlet side B of drum 21. Also located at the inlet side A is inlet 28 for heated humidified air and at outlet B spent air exit 29. Nozzles 31, 32 are provided for supplying additional moisture to the tobacco leaves as they enter drum 21. At the discharge end of drum 21 tobacco is collected onto a shaker conveyor trough 38 containing a measuring capacitor 37 which form part of a transducer 39 for determining the final moisture content of the tobacco. Air conditioning chambers, valves, thermometers and sensors ensure that the throughput of moisture is commensurate with the throughput of tobacco.

Abstract: 1326245 Foundry moulding machines; coating patterns/core-boxes EARL A THOMPSON MFG CO 12 Aug 1970 [28 Aug 1969] 38938/70 Heading B3F Coating patterns/core-boxes.-A metal pattern (core-box) 10 for forming a foundry moulding is provided with a throughbore 18 and a cavity for forming a moulding (as shown, 4 cavities 16) in the throughbore. Parting agent dispersed in a gas (e.g. superheated steam) is introduced into the throughbore 18 at opening 22 from a nozzle 28 and vented from the pattern 10 at an opening 20 through an aperture 30 of smaller crosssection than the throughbore 18, to retard the flow of parting agent to allow it to be deposited on the pattern surfaces. To ensure even coating of the pattern, parting agent may subsequently be blown into the opening 20 of the pattern and vented through the opening 22. Blowing of parting agent through opposite openings of the throughbore 18 may be effected alternately after each moulding cycle in the pattern. Foundry moulding machines.-Moulding may be effected by blowing or otherwise forcing fluidized sand (e.g. resin coated sand) into the pattern. The pattern 10 may be mounted on a rotating table 60 (Fig. 12) and presented sequentially to stations for coating, introducing moulding material, curing the moulding and ejecting the moulding. As shown in Fig. 12, sand from a reservoir (92, not shown) enters an L- shaped blow-box 94 through a sand valve 112 and air is vented from the blow-box 94 through a valve 142. The sand is fluidized by air from a nozzle 150 and blown through a rubber (95)- tipped nozzle 36 into the pattern 10 by air entering the blow-box 94 through a pipe 174. Alternatively, the fluidized sand is introduced into the pattern by centrifugal force obtained by rotating an elongate sand box (not shown). The sand-blowing assembly is pivotable about a horizontal axis so that it may be tilted away from the pattern 10 to allow the table 60 to rotate. As shown in Fig. 6 a double nozzle 36, 36<SP>1</SP> may be employed to blow sand into the pattern 10. Otherwise, a single nozzle is employed and one end of the throughbore is closed.

Title: Apparatus for breaking off and stacking upwardly drawn glass sheets
Inventor: AKSNES NILS
IPC: B65G49/06
Filed: 1961-11-02
Abstract: <PICT:0968514/C1/1> To break off and stack upwardly drawn glass sheets G, a clamp K is operated to grip the upper edge of the sheet by a pneumatic or hydraulic piston-and-cylinder S1 controlled by engagement of a device Q on the clamp K by the upper edge of the sheet, the cylinder S1 being mounted by a coupling P on the piston-rod M of a cylinder S2 which is then operated to move the clamp K upwardly to the desired position at which a scoring device D scores the sheet G transversely, the cylinder S2 being mounted on a cylinder S3 for movement along the piston-rod N by rollers LK engaging a beam B, such movement, by fluid to cylinder S3, immediately following the scoring of the sheet and thereby breaking the sheet along the score line, the sheet then being lowered by operation of cylinder S2 to stack the sheet.  The fluid to cylinder S3 takes the sheet to a position over a contact H on to which the sheet is lowered. The contact H operates to admit fluid to a further cylinder S4 having a piston also on piston-rod N, so that the cylinders S3, S2 and S1, the clamp K and glass sheet G are moved further in the direction R2 to move the sheet over a rack E.  A contact on cylinder S4 then initiates a further lowering movement of rod M, so that the sheet G engages a support F on rack E, and also operates a cylinder S5 which moves a lever A so that a pad pushes the sheet to the oblique position shown at G1, the coupling P being such as to allow a certain play between the rod M and cylinder S1. A contact in the coupling P then returns the cylinders and clamp to the initial position to receive the glass sheet G.  Guiding rollers V for the sheet G are provided, one being swingable to an out of the way position as the cylinder S3 is actuated.  The rack E is symmetrical to allow stacking on both sides and on rollers for easy removal.  A timer synchronizes the movements of the breaking device and moves the cylinder S1 up at the same rate as the drawing device for the glass sheet.

Abstract: 1,026,810. Vehicles capable of leaping over obstacles; air cushion vehicles. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. Nov. 17, 1961 [Nov. 18, 1960; Aug. 30, 1961], Nos. 39833/60 and 31277/61. Headings B7K and B7W. An air jet thrust supported vehicle has means providing a vertical thrust of a magnitude less than the weight of the vehicle but temporarily exceeding that required for hovering, thus enabling the vehicle to leap above the steady hover height, and means imparting a forward speed to the vehicle, which is thus capable of leaping over obstacles of a given length and height. In one embodiment (Fig. 6 of Provisional Specification 39833/60), a cross-country army reconnaisance vehicle runs on the ground on four road wheels 2 driven by a conventional car engine and has a gas turbine 4 driving its own compressor 5 and an auxiliary compressor 6, which compressors have air intakes 7 and 8 respectively at the front of the vehicle. The exhaust from the turbine 4 is discharged downwardly through an adjustable nozzle 9 to produce propulsion or retardation as desired. The flow through this nozzle 9 forms part of a jet curtain which is completed by the flow through arcuate lifting nozzles 12 arranged along the perimeters of segment-shaped hinged wings 10 and by that through a front nozzle 17. The nozzles 12 and the nozzle 17 are supplied with compressed air from the auxiliary compressor 6 through ducts 13 and 16 respectively. The wings 10 may be folded up for travelling on the ground or for storage. The front nozzle 17 and others (not shown) are controlled by means of valves by the driver in order to stabilize the vehicle in its leap. In another embodiment the road wheels are again driven by a car engine while a gas turbine is geared to two multi-blade rotors journalled about vertical axes in ducts which are circular at their intakes but have the shape of two opposed horse-shoes at their outlets, being separated from one another by a longitudinal central island. The rotors have adjustable pitch blades and when the vehicle approaches the obstacle to be cleared while running on the road wheels with the gas turbine operating and the rotor blades feathered, the blades are suddenly set to a coarse pitch and the vehicle becomes airborne.

A lay shaft (not shown) has a pair of gears in constant mesh with the gears 4, 5 whereby low ratio through the lay shaft is obtained when the member 6 is engaged with the gear 4, and direct drive from the main shaft to the gear 5 is established when the latter is engaged by the member 6. Upshift is effected by the spring 20 on release of the trip means by a Bowden cable 18 connected to a handle bar control, and downshift by clockwise movement of a gear lever 14 welded to the member 11. Fig. 2 shows the selector means in the intermediate neutral position. The mating dog clutch projections 22, 23, 24, 25 are shaped as shown in Fig. 4 to promote disengagement of the member 6 from the gear 4 and its engagement with the gear 5. Preferably the trailing edges of the projections 22, 23 are also shaped to promote disengagement on overrun. One of the main shaft gears and the meshing lay shaft gear may be readily replaceable to change the low ratio.
